Substitute Part Grouping Explanation

Substitute parts for the PCF14JB1M00 are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1 MOhms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Composition: Carbon Film (exact match)
• Temperature coefficient: 0 / -1500ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match or better)

Mechanical Equivalence Requirements:

• Package type: Axial (exact match)
• Physical dimensions: 0.091" Dia x 0.236" L / 2.30mm x 6.00mm (exact match)
• Number of terminations: 2 (exact match)

Compliance & Feature Requirements:

• Flame retardant coating and safety features (must be present)
• ECCN and HTSUS classifications (must match for regulatory purposes)

Substitute parts meeting all these criteria are functionally and mechanically interchangeable without circuit redesign or PCB layout modification.
